Constructing a Circle

1. Choose the Compass tool if it’s not already active.

2. Click to locate the center of your circle. (You can click in empty space, on an existing point, on a path object such as a segment or another circle, or on an intersection.)

3. Click again to locate the radius point.

Another way to use the Compass tool is to press the mouse button at the center point, drag, and release the button at the radius point.
